To provide greater security on Android, Samsung has developed the KNOX – a mobile security platform which can make the Galaxy S4 more appealing for use as an enterprise device and stronger Apple iPhone 5 competitor. This feature lets users set multiple levels of security and keep personal data separate from official data on their Galaxy S4 smartphones.
There are essentially three separate layers of security on the Galaxy S4, thanks to Knox – Secure Boot, ARM TrustZone-based Integrity Measurement Architecture (TIMA), and a kernel with inbuilt security enhancements for access controls. The first level ensures that no unauthorized apps get installed on the Galaxy S4, which could put user data at risk. TIMA provides constant monitoring of the Android OS and can disable the kernel or shut down the device in the event of a security breach.
The third level, security enhancements, keeps app data separate and isolated from each other to ensure greater security for any confidential content on the device. This can help minimize or prevent any damage caused due to any security attack too. It could give a great boost for considering the Galaxy S4 as a device for BYOD programs in organizations.
